Physiological effectors for mitogenic cell growth control remain to be determined for mammalian tumor cells, particularly those derived from prostatic tissue. One such effector for mitogenic Ras/MAPK signaling in fibroblasts is an intermediate-conductance, calcium-activated potassium channel (FIK).
The usefulness of prophylactic diuretic therapy with furosemide was investigated in 6 patients with stages III and IV prostatic cancer who were undergoing diethylstilbestrol therapy. A significant increase was noted in sodium and water excretion, whereas outputs of chloride and potassium, and serum
Potassium ion channels are a complex of protein molded in the cell membrane lipids. Its expression is strong in normal prostatic epithelia and weak in different degrees in prostatic cancer epithelia, but not clearly known in chronic prostatitis epithelia. Drugs affecting potassium ion channels could
Mice bearing a 3-methylcholanthrene-induced fibrosarcoma (MCAM-7) transplant in the right leg underwent surgical excision of the tumor and showed specific resistance to subsequent challenges with that identical tumor line. An in vivo response to tumor-specific antigens (MCAM-7 antigen) solubilized
Estramustine (EM), a complex between estradiol-17 beta and nornitrogen mustard, is commonly used in the treatment of prostatic cancer. The exact mechanism of action is unknown but has previously been considered to be mediated through non-DNA targets, specifically with the mitotic spindle, and to be
Estramustine phosphate (EMP), a complex between estradiol-17 beta and nor-nitrogen mustard, commonly used in treatment of prostatic cancer, also exerts marked antiproliferative effects on cultured human malignant glioma cells. The mechanism of action is unknown but has previously been considered to
The demonstration of 0-acylated sialic acids in the mucin of cancer metastases by Culling's periodic acid-borohydride-potassium hydroxide-periodic acid-Schiff method (PB/KOH/PAS) is helpful in distinguishing between mucin-producing primary colorectal adenocarcinoma (which will be in 60 to 70%
Specific receptors for dihydrotestosterone and estradiol-17-beta have been identified in cytosols of the human and baboon prostate. Binding of radioactive estradiol-17-beta to the 0.4 M potassium chloride extractable component of human prostate nuclei also was demonstrated. Cyproterone acetate and
Gossypol, a polyphenolic aldehyde naturally present in cottonseed, has long been recognized as a male contraceptive and recently as a potential anticancer agent. Our study used a rodent model to evaluate gossypol's potential for the treatment of human prostatic carcinoma. Two-month-old Copenhagen
